Genes affected
CMBL (HGNC:25090): (carboxymethylenebutenolidase homolog) CMBL (EC 3.1.1.45) is a cysteine hydrolase of the dienelactone hydrolase family that is highly expressed in liver cytosol. CMBL preferentially cleaves cyclic esters, and it activates medoxomil-ester prodrugs in which the medoxomil moiety is linked to an oxygen atom (Ishizuka et al., 2010 [PubMed 20177059]).[supplied by OMIM, Apr 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2022The c.206A>G (p.N69S) alteration is located in exon 2 (coding exon 1) of the CMBL gene. This alteration results from a A to G substitution at nucleotide position 206, causing the asparagine (N) at amino acid position 69 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
